Sinonine improves the structure of autogenous mill to
The autogenous mill for quartz sand processing includes the cylinder, the cylinder is connected with a discharge cylinder, the inner cavity of the cylinder is provided with a grid plate, on the grid plate are a number of discharge holes for screening the materials after autogenous grinding, the cylinder is also provided with a dustpan plate for conveying the screened materials to the discharge cylinder; the autogenous mill The milling circuit analyzed here consisted of a fully autogenous closedloop mill with a recycling load that overflowed from a screen unit, as indicated in Fig 1 The circuit was under expert control, which manipulated the mill’s control variables, namely its water inlet, coarse ore feed rate and fine ore feed rate, to control the output variables of the mill, ie the mill load and the power consumption of the millVisualization of the controller states of an autogenous A SAG mill has low speed and heavy load, which cause the energy consumption of grinding operation to be very high It accounts for a large proportion of the electrical consumption across the plant [3] The rotation speed is an important factor related to the operation and grinding e ciency of the millOptimal Speed Control for a SemiAutogenous Mill Based
